My husband is an American from Taiwan Province Province, and I am a mainlander. Can I travel freely to Taiwan Province Province?

You can try the procedure of visiting relatives in Taiwan Province.

Your husband should have dual nationality (the United States and Taiwan Province Province), because his parents are both from Taiwan Province Province, and according to the nationality law of Taiwan Province Province, he is naturally from Taiwan Province Province (nationalism); And he should have been born in America (territorialism), so he has dual nationality.

You are married to your husband, but you are only registered in China, but this is not the way. You have to go through the second half of the procedure and let your husband register in Taiwan Province Province or the United States as Taiwan Province Province or the United States. I suggest you enter the United States first, followed by Taiwan Province Province. At that time, you can enter Taiwan Province with a photo of an American household registration, or enter Taiwan Province with the "Pass for Mainland People to and from Taiwan" (before you get a Taiwan ID card).

Taiwan Province province can get married only after completing the marriage registration! If it has not been completed, we can consider the second way of crossing the border mentioned by LS.
